Ellie's a better character, but it's literally just once kiss, between two kids, after hanging out with her "best friend". Other than not they didn't explore her orientation one bit, with Bill they thing between him and his partner was deep, and the comedy at the end with the porn was funny. So while Ellie's miles ahead as a character I'd give Bill
But he is canonically bisexual (well, after the release of ME3 anyway). I think having some bixesual, transgender characters representing is also a good thing
